Voicemail Error

When I start Asterisk the CLI gives this error for every extension

ERROR[21644]: app_voicemail.c:2491 inboxcount: Couldn’t find mailbox 2992 in context default

Here is the contents of my voicemail.conf

format=wav

imapserver=192.168.8.15
imapport=143
imapfolder=Voicemail
imapflags=notls
authuser=Admin
authpassword=Password

[default]

2992=>2992,Test,imapuser=test|imappassword=pass

I am running Asterisk 1.4.9

Any Ideas would be appreciated.

Thanks,
Erik
